' SPECIFICATION forming part of Letters I'atent No. 549,796, datedNovember 12, 1895.

Application filed July 23, 1895. Serial No- 556 ,9l'7. (No model.)

ToaZZ whom it may concern.-

Be it known that I, DANIEL AUGUSTUS KEL- LER, of Rincon, in the countyof Donna Ana and Territory of New Mexico, have invented a new andImproved Railway- Car J aok, of which the following is a full, clear,and exact description.

The object of the invention is to provide a new and improved railway=carjack which is simple and durable in construction, and more especiallydesigned for conveniently removing worn-out brasses in the journal-boxes of the car-axles and replacing the same by new ones, or toraise the box or other apparatus without disturbing the position of thewheel on the track.

The invention consists principally of a supporting-frame adapted to behung on the carwheel, a screw-rod screwing in the said frame, and across-bar held on the said screw-rod and provided with arms adapted toengage the journal-box.

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of the improvement. Fig. 2 is a sideelevation of the same, and Fig. 3 is a reduced side elevation of theimprovement as applied.

The improved railway-car jack is provided with a supporting-frame A,having a threaded bar A, from the ends of which extend transverselyhooks A adapted to engage the top of the wheel B, as is plainlyillustrated in Fig.

3, so as to support the said frame from the car-wheel. In the threadedbar A screws a screw-rod O, on the lower end of which is hung across-bar D, provided at its ends with depending angular arms E, adaptedto engage the truck-frame, as well as the under side of the journal-boxF for the wheel B. The angular arms E are mounted to be turned in thecross-bar D to carry their lower transversely-extending arms E under thebottom of the journal-box to properly engage the same.

When the several parts are in the position shown in Fig. 3, theoperator, by turning the screw-rod O with a suitable tool engaging theapertured head 0, causes a screwing up of the said screw-rod in theframe A to lift the cross-bar D, and, by the arms E, the journalbox F.In doing so the worn-out brass may be readily taken out of thejournal-box and replaced by a new one, and the screw-rod C then turnedin an opposite direction to lower the crossbar D, arms E, andjournal-box F until the brass is properly seated on the journal.

It is understood that the jack may be used for other purposes thanreplacing brasses, it being understood, however, that the position ofthe wheel B is not disturbed while the box F is raised. 1

The lower end of the screwrod O is mounted to turn in the cross-bar D,so that on screwing up the screw-rod, the bar D is then raised orlowered, according to the direction in which the screw-rod is turned.The hooks A of the frame A are shaped in such a manner as to fit on thetread and flange of the wheel, as will go readily understood byreference to Fig.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A railway car jack, comprising a supporting framehaving a threaded bar, hooks extending from the ends of the said bar andadapted to engage the top of a car wheel, a screw rod screwing in thesaid threaded bar, a cross bar held on the lower end of the said screwrod, and arms mounted to turn in the said cross bar and adapted toengage the journal box of a car axle, substantially as shown anddescribed.

2. A railway car jack, comprising a frame having a threaded bar, hooksrigid with the said bar and extending transversely from the endsthereof, the free ends of the said hooks being shaped to fit the treadand flange of a car wheel, a screw rod screwing in the said threadedbar, a cross bar hung on the lower end of the said screw rod, anddepending angular arms having their upper ends mounted to turn in theends of the said cross bar and adapted to engage with their lower hookarms the under side of the journal box of the car axle, substantially asdescribed.
